Algebra 1 Unit 4 Functions Recovery Assessment

Front

What is the definition of a function?

Back

A function is a relation where every input has only ONE output.

Front

Is this graph a function or not a function? (Graph shows a vertical line test)

Back

Function

Front

Is this mapping a function or not a function? (Mapping shows multiple outputs for one input)

Back

Not a Function

Front

What are all of the y values or outputs called?

Back

Range

Front

Which set of values is a function? (9,5) (10,5) (9,-5) (10,-5), (3,4) (4,-3) (7,4) (3, 8), (6,-5) (7, -3) (8, -1) (9, 1), (2, -2) (5, 9) (5, -7) (1, 4)

Back

(6,-5) (7, -3) (8, -1) (9, 1)

Front

What is the domain of a function?

Back

The set of all possible input values (x-values) for a function.

Front

What is the range of a function?

Back

The set of all possible output values (y-values) for a function.

Front

What does it mean for a function to be linear?

Back

A linear function is a function that graphs to a straight line.

Front

What is the slope of a line?

Back

The slope is the ratio of the rise (change in y) over the run (change in x).

Front

What is a vertical line test?

Back

A method to determine if a graph represents a function; if a vertical line crosses the graph more than once, it is not a function.
